[quote user="Romy the Cat"]It is was not bad sound but the sound that clearly indicated that something is very wrong: supper compressed, complete absent of LF, huge HF extension. The whole horn sounds like a bad MD driver.[/quote]Open the back panels...

Hm…m… I do not know how about that.
Well, the SG146XX
where the most interesting from one perspective and the most problematic from
another perspective. Goto, never gave to SG146 an option to moderate resonance
frequency and without it I feel i...

We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

[quote user="coops"]Ralph and Thomas are friends there would have been no price premium for the field coil option …[/quote]Considering that Cessaro claims that they pay for $500 worth TAD drivers (OEM) over $5000 then I might only imagine how much pr...

Ralph (Cessaro) is in the process of manufacturing his own compression drivers, I have no details as yet, I believe the diaphragms will be beryllium not made by TAD.Also new and ready for release ,although not shown at Munich are double skinned carb...

ltsv38, it is an interesting solution for lower midrange horn. If I use something like this for Macondo ‘s fundamental channel (but of cause spherical) then I would flip the horn with driver up and run the neck longer to accommodate a slower, expone...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

Hi thereFor some time its bugging me that compression drivers got a very heavy but odd load of air coupling on the membrane. I saw a scatch here to put ideally 2 Horns on each side of the driveway to balance it. That's obviously not so economically :...

Josh, I do not have a
definitive answer to this question with witch I feel comfortable. I need to say
that I had a multiple experiments in multiple audio fields and I always felt
that excessive or too limited magnetic force is not always complimen...

I've been thinking about this matter for a while but could not find a better excuse to formulate my theory then in this topic. My simple theory is that if we reduce our concept of "music" the more fundamental concept of "sound" as point of reference ...

There are a few at least theoretical backdraws for the Array in my view.Of course having a lot of different drivers playing at the same frequency implies that all of them should work in perfect unison, if one starts lagging a little bit it will mess...

I take it back, 100Hz is pushing it regarding horns and compression drivers I know of. I can't imagine a compression driver reaching the midbass muscle of the Fane S 8M. And I don't see why one should try, when the Fane reaches 120Hz so effortlessly....

[quote user="Jorge"]I tend to like drivers with plastic suspension. Radian makes retrofit diaphragms for JBL with plastic suspension, maybe they will help you achieve the tone you are looking for.
Extensions are easy to machine out of aluminum, eve...

I am quite fascinated with the result that I might get from MiniME and at the same time I am defensive with the direction it takes. Anyhow, here is how it stands…
The decision to go for MF driver was I think right one. Even the 70-20RX tweeter has s...

[quote user="msaudio"]If you look at the picture second from the the top, you will see 2 woofers mounted in front on the baffle, notice a 2 piece horn from the baffle. Klangfilm never had such a horn, they would start at the baffle and curve out. The...

Thanks Gregm. It is interesting that I completely forgot the TAD PT-R9. I was looking at it 5-6 years back and spoke with AudioKinesis ‘Duke, who reportedly knows them well. My reservations that time were the very same as now: with 97.5 dB/W sensitiv...

I do not know any advantages because the fact that the sound softer. I personally believe that the electromagnets have HIGHER MOMENTUM FLUX MODULATION and that make them to “sit” slightly… or exactly what I would like t...

One of the main advantages of Macondo configuration was the fact of multi amplification. As with any other systems which have a dedicated amplifier of the same type to each individual driver Macondo can run over dynamic range with amazing ease th...

[quote user="cv"] Well, the Cogent (Steve Schell and Rich Drysdale) boys are building just such a beast: field coil magnet, (possible) permendur polepieces for >2T, Fs 70Hz, throat - dunno, but at least 3" dia, reduced compression ratio relative t...

They have a 17cm throats so in most cases it is better to get the version with 2" throat for compression drivers, shorten them for the right throat size and build a chamber yourself....

Sorry I misread, I thought you endorsed the use of PP tube amps with compression horn drivers. Well it looks like were still in the same situation of not making them work. I could go on about why I feel they don't work, but it won't chang...

[quote user="RonyWeissman"]The electricity comment is interesting as today I put on some jazz music and the HF is very snappy, excellent! I feel like posting on AA to ask people's opinons if it's the electricity or if my concrete horns are going thro...

Romy Hi, I do not know how the Alphas are configured crossover wise or how much 'sonic mad' they use, Avantgardes do not use compression drivers of course just slightly modified conventional cones ( I believe ) I have heard AG Trios the Cessaros are ...

If you ask me the compression drivers is like the jbl 2420/2470 design only with an other back chamber. And the low freq driver really makes me think of an old alnico driver of jbl 2220A http://www.lansingheritage.org/images/jbl/specs/pro-comp/2420/p...

there is one system that resembles what live music sounds like and its not a horn! :)To be honest I really have no idea of what topology these horns were setup like... all i have evaluated is there soundI like to go into something without any prejust...

I guess you cannot say you listened to a horn system if you dont have an upper bass horn.The upper bass horn has to fill in the response from the compression driver down. At this delicate range nothing will perfectly macth it but another front horn. ...

Taming strange fullrange drivers is fun, doesn't cost an arm and a leg and there is always room for a second, third, etc. system. E.g. what to do with such a ridiculous unit? http://www.ciare.com/pdf/catalogo/HX135.PDFBack-loading? No problem when th...

[quote user="noviygera"]p.s from my experience of having a 500 sq. ft. listening room with 7 ft. ceiling and having two 18" woofers in a infinite baffle configuration, it is not enough to pressurize the room. I am talking about low and medium listeni...
